BOLT.

Specification of Letters Patent.

.l'atented Mar. 4, 1913.

Application flled October 28, 1911. Serial No. 657,244.

To all whom, it may concern Be it known that l. lianannca llonnnn, a citizen of the United States, residing at Montezuma, in the county of Summit and State of Colorado. have Invented new and useful Improvements in llolts, of which the l'ollowing is a specification.

This invention relates to improvements in bolts.

lu carrying out. my invention it is my purpose to provide a bolt especially adapted for use l'or securing tlights or buckets to conveyor bclts and one wherein the necessity of punching or cutting the belt for. the reception of the bolt is entirely obviated.

I also aim to provide a bolt of this class which may be readily forced through the belt of the conveycrs, thereby bracing the material of which the belt is formed and avoiding the danger of weakening said belt, incident to cutting or perforating the same.

With the above, and other objects in view, the nature of which will be disclosed as the description of the invention progresses, the invention resides in the novel construction of bolts for securing flights or buckets t0 convcyer belts as will hereinafter be more fully described and claimed.

In the drawings, Figure 1 is a perspective view of the bolt constructed in accordance with the present invention. Fig. 2 is a sectional view through the belt or conveyer, showing the bolt. in its applied position thereon and securing thereto a bucket or llight.

.ln the well known manner of connecting [lights or buckets to conveyers, a hole is made in the belt by cnttin or punching a part of the belt, this hole Is for the reception of an ordinary bolt and it is obvious that by thus cutting away the belt, it is wealwned at these. particular points and as aconseqla-nce easily severed when under a strain. This requires the mending of the belt which, ol" course, requires quite an amount of time and labor, not to swak of r the time and expense occasioned by t 1e nonworking of the belt.

It is the primary object of the present in- 5\ vention to provide a. bolt having a sharptned or V-shaped edge, and also provided ith a head formed with bltmg teeth the sharpened terminal of the bolt being readily forced through the belt which compresses the portion of the belt surrounding the bolt, and which, instead of weakening the belt, adds to the strength thereof.

Referring now to the drawings in detail, the numeral 1 designates an ordinary conveyer belt, and 2 the. bucket or flight to be connected with the belt.

The numeral 3 designates my improved bolt. This bolt embodies a shank 4, and a head 5. The shank 4 is rounded in cross section and is provided with threads 6. The end of the shank opposite its head 5 is bevelcd in opposite directions to provide a sharpened extremity 7. The head 5 is formed upon its inner face with a plurality of integrally formed teeth 8. B reference to Fig. 2 of the drawings it wili be noted that one pair of diametrically op )osed teeth 8 are of a width greater than t lat of the shank, while the remaining teeth are smaller but have their biting edges arranged in par- 'allel planes with the first named teeth. It will be further noted by reference to Fig. l of the drawing, a pair of the teeth 8 are arranged in alinement with the beveled portions of the shank terminal, and have a length exceeding the diametrical extent of the said shank. After the shank is inserted through the belt and the teeth of the head thereol' engage the said belt, a nut 9 is screwed upon the threaded portion 6 of the shank the flightbeing arranged between the said nut and the conveyor belt.

Having thus described the invention what I claim is:-

l. A bolt. t'or conveyor belts, comprising a threaded shank, having a sharpened terminal and an enlar ed head disposed at right angles to the tank, said head being formed with sets of diametrically opposed teeth havim biting edges, the bitin edges of all of said teeth being arranged 1n parallel planes, and one pair of such teeth being of materially greater length thanthe remaining'teeth.

2. A bolt for conveyor belts, comprising a shank having diametrically opposed portions thereof cut away to form a beveled sharpened terminal, and a head formed integrally with the. opposing end of the shank and provided with teeth having biting edges, In testimon whereof I aflix my signature said tegth being alganhged in diametrically in presence 0 two witnesses.
